Andrology

Andrology sits at the intersection of vascular, hormonal and autonomic function. Erection is parasympathetic (S2–S4); ejaculation is sympathetic (T11–L2). When the autonomic nervous system (ANS) is locked in chronic sympathetic dominance, neither pharmacological nor hormonal therapy can fully restore the response — because the operating system governing sexual function remains in defence mode.

Non-invasive neuromodulation with NESA XSIGNAL® targets the spinal segments involved in sexual function and continence, helping restore sympathetic–parasympathetic balance. It does not replace your pharmacological toolkit: it enhances its effectiveness.

Treatment

Non-invasive neuromodulation with NESA XSIGNAL® acts directly on the autonomic nervous system, supporting processes that influence pain, tone, inflammation, microcirculation and sleep quality.

By targeting autonomic regulation, it may help reduce hyperreactivity, improve physiological variability and promote more efficient recovery between sessions.

It integrates as a supportive component within the treatment plan, without interfering with other interventions, and can be tailored to the patient’s profile: symptoms, sleep, pain, stress levels and load tolerance.

Functional objectives

  • Improved sympathetic/parasympathetic balance.
  • Better sleep and more restorative rest.
  • More efficient recovery between sessions.
  • Greater adherence to, and progression within, the treatment plan.

Applications

Common Clinical Presentations

  • Erectile dysfunction and male sexual function.
  • Prostatic symptoms / chronic prostatitis.
  • Chronic pelvic pain.
  • Functional urinary symptoms (urgency, frequency, pain).
  • Elevated physiological stress / hyperarousal.
  • Sleep disorders.

As Support for Recovery Processes

  • Inflammation and edema.
  • Support for microcirculation and tissue perfusion.
  • Autonomic dysregulation (sympathetic/parasympathetic imbalance).
  • Sleep disorders.

Benefits

  • Reduced hyperreactivity and enhanced stress regulation.
  • Improved sleep and recovery.
  • Support for microcirculation and peripheral vascular comfort.
  • Complementary, non-invasive and drug-free support.
  • Individualised protocols tailored to symptoms and autonomic profile.

Introducing NESA XSIGNAL®

NESA XSIGNAL® is a non-invasive neuromodulation system that applies very low-intensity microcurrents through electrodes, with protocols oriented towards regulation of the autonomic nervous system. It is designed to integrate into clinical practice as part of the multimodal approach.
In Andrology, the protocols act specifically on the sympathetic–parasympathetic balance in the spinal segments that control sexual function, continence and male pelvic pain.

Testimonials

“NESA is a promising tool in urology, sexual health and pelvic pain, with an integrative and collaborative approach. We don’t treat organs, we treat people, and NESA opens new ways to improve their quality of life.”
The impact of regulating the ANS in andrology
When specific work on the autonomic nervous system is incorporated, the effect is often systemic: reduced physiological “noise”, more consistent recovery and improved adaptive capacity. In andrology, this may translate into:
Supporting autonomic balance may expand the patient’s adaptive capacity, allowing local interventions such as manual therapy, exercise or procedures to be better tolerated and more consistent over time.
